The company has reportedly been testing two replacements for the favorite option, called "star" and "like." So far, it appears that the changes are limited to only a few users, so it's not clear if the function works any differently.

Favorites have been on Twitter for several years. According to The Next Web, which first reported on the testing, a source told the publication that the feature has been used "billions of times."

In its current implementation, clicking the "favorite" option lets users save a tweet. From there, the listing is available whenever they want to refer back to it.

If Twitter decides to switch to "like," it might catch the eye of Facebook. That social network has relied on likes for years to increase engagement across its service. To see a competitor use the same word might be a problem.

CNET has contacted Twitter for comment on the testing. We will update this story when we have more information.
